Hi, I was wondering whether it was possible to conduct a three step regression (in which the covariates are predictors of latent class membership), where the latent classes are based on a joint LCGA and survival analysis?

I am conducting a survival analysis and looking to use latent class analysis with the 3 Step methods. How can I go about implementing the 3 Step method in survival analysis? I have not found any published examples. Any help is much appreciated.

It may be that the following paper is more relevant given your survival outcome:

The posted version corrects several typos in the published version. An earlier version of this paper was posted as web note 15. Download appendices with Mplus scripts.
